Deletes several live or archives sessions from the server. If the client is not sure whether the client has permission for it, it can set the SkipForbiddenSessions - the server will skip disallowed sessions instead of rejecting the entire operation.
A future that will contain the server's response (and optionally which sessions were skipped due to permissions)
